Question 1: If a packet matches a route-map statement configured with 'deny', processing continues to the next statement to find a 'permit' action.
A. Ano
B. Ne
Explanation: When a route-map statement matches, processing stops for that packet/route, regardless of whether the statement is 'permit' or 'deny'. It does not continue to the next statement to find another match.
Question 2: When a route-map with a single permit statement that uses an access-list with a single deny statement (e.g., deny 192.168.0.0/24) as its match condition is applied to filter EIGRP routes, only the networks explicitly denied by the access-list will be processed by the route-map statement, while all others are permitted.
A. Ano
B. Ne
Explanation: When a route-map has a permit statement and its match condition refers to an access-list with a deny statement for a specific network, the access-list will deny that specific network and implicitly deny everything else. Because the access-list has no permit statements, nothing will be matched by the route-map's permit statement, leading to all routes being dropped by the route-map's implicit deny.
Question 3: A route-map includes an implicit deny at its end, similar to an access-list.
A. Ano
B. Ne
Explanation: Route-maps process statements sequentially and if no match is found, they hit an invisible implicit deny at the bottom, just like access-lists. This means that if no permit statement explicitly matches a condition, the traffic or route will ultimately be denied.
Question 4: When configuring a route-map, it is only possible to specify either an access-list or a prefix-list as a match condition, not both.
A. Ano
B. Ne
Explanation: The study materials state that route-maps can match on many different items, including prefix-lists and access-lists. The section 'Multiple Match Conditions' explicitly demonstrates matching multiple access-lists in a single route-map statement, indicating that it's possible to use multiple match conditions, not just one or the other exclusively.
Question 5: A route-map can be applied to a distribute-list in EIGRP to filter networks advertised by a router.
A. Ano
B. Ne
Explanation: The study materials state that a route-map can be attached to a distribute-list in EIGRP, which allows filtering of networks that a router advertises.
